Enter the page thickness (mm) and the number of pages into the Calculator. The calculator will evaluate the Spine Width.

## Spine Width Formula

SPW = TP * P

Variables:

• SPW is the Spine Width (mm)
• TP is the page thickness (mm)
• #P is the number of pages

To calculate Spine Width, multiply the page thickness by the number of pages.

## How to Calculate Spine Width?

The following steps outline how to calculate the Spine Width.

1. First, determine the page thickness (mm).
2. Next, determine the number of pages.
3. Next, gather the formula from above = SPW = TP * #P.
4. Finally, calculate the Spine Width.
5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem :

Use the following variables as an example problem to test your knowledge.

page thickness (mm) = 5

number of pages = 6
